RAIL FOR CARRIAGE-SEATS.

SPECIFICATION forming part of Letters Patent No. 418,460, dated December 31, 1889.

Application filed June 7, 1889. Serial No. 313,431. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM F. HEAD, of Cortland, in the county of Cortland and State of New York, have invented certain new and useful Improvements in the Manufacture of Shifting-Rails for Carriage-Seats; and I do hereby declare that the following is full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to the manufacture of the so-called shifting-rails of carriageseats, which rails are extended along the sides and back of the seat a short distance outside of the top thereof and support the top of the carriage; and the invention consists in an improved method of forming the corner-sections and side rails of said shifting-rail, as hereinafter fully described, and specifically set forth in the claim.

In the annexed drawings, Figure 1 is a plan view of a carriage-seat with the shiftingrail attached thereto. Fig. 2 is a front view of the same. Figs. 3, 4, 5, 6, and 7 are plan views of the blank from which the cornersection of the shifting-rail is formed, and showing the difierent forms produced by the successive steps of the process of manufacture; and Fig. 8 is a detached perspective view of a modification of the eorner-seetion of the shifting-rail.

Similar letters of reference indicate corresponding parts.

A A and A represent, respectively, the two side rails and back rail of the shifting-rail surrounding the top of the seat D, as hereinbefore stated, and secured to metallic brackets Z Z, attached to the seat in the usual and well-known manner.

My invention pertains, specially, to the construction of the side rail A, which is composed of the following integrally-united parts, viz: the central section Z), front end section 0', formed with the laterally-extending arm 0', rear end or corner section C, formed with the stub f,by which it is welded to the back rail A, and with the laterally-extending arm 0 and attaching-eyes a a at the junction of the central section b with the end sections C 0.

Prior to my present invention it has been customary'to form the central section b with the eyes a a and with a stub extending from the rear eye, and the corner section C was formed with a short stub in front of the arm 0, and the two parts I) and C were united by welding the said stubs to each other. In practiceI have found it very difficult to effect a good weld so near to the arm 0 and eye a, and owing to the shortness of the distance from the eye a to the rear end of the side rail very little opportunity is aiforded for either drawing out or upsetting the iron to obtain the exact length required of the said portion of the side rail.

The object of this invention is to overcome said diiiiculties; and to that end my invention consists, essentially, in forging the two sections 0' 0 each with one of the attaching lugs or eyes a a and with a portion of the central section b, and then welding the said portions of the-central section to each other. The said end sections I produce by the forging process hereinafter described, and inasmuch as there is a considerable distance between the two attaching-eyes a a of the side rail A, I am enabled to form the two end sections 0 l, with portions of the central section b, of ample length to facilitate the welding of the same to each. other, and in such a manner as to bring the eyes a a the requisite distance apart, and by joining the aforesaid parts ata point between the attaching-eyes a C6 said joint is carried between two supports on the seat, and is consequently greatly relieved from the strain incident to the weight of the carriage-top mounted on the usual arms 0 c of the side rail A.

The front end section 0, I forge in the usual manner, with the exception that I form it with only a portion of the central section b. The corner-section or rear end section 0 of the side rail A, I form by forging a blank Z), which is in line with the main portion, and by which it is to be joined to a portion of the central section 1), formed integral with the front section 0. On the opposite end of the aforesaid main portion of the blank I forge the arm 1' and the Welding-stub f, extending in opposite directions therefrom, as shown in Fig. 6 of the drawings. To produce this blank and finish the same, I preferably resort to the following preliminary steps and final steps in the process of manufacturing the cornersection O, to wit: I first forge a blank with the side enlargement f on the central portion thereof, and with the approximately-cylindrical enlargement g near one end of the enlargementf, as shown in Fig. 3 of the drawings. I next split the enlargement flongitudinally from one end part way the length thereof, as shown in Fig. 4 of the drawings. I then spread the cleft h of the enlargement f from the main portion of the blank and bend toward the opposite side of the latter the end portion i adjacent to the fixed end of the aforesaid enlargement, as illustrated in Fig. 5 of the drawings. I then bend the portions f and t'still farther, so as to set them at right angles to and in opposite directions from the main portion of the blank, as shown in Fig. 6 of the drawings, and in this condition I place the blank between suitable dies of a droppress, and by the impact of said dies I round the edges of the blank, as represented in Fig. 7 of the drawings. The portion 1' forms the arm 0 for supporting the carriage-top. The stub b constitutes a portion of the central section of the side rail A and is welded onto the portion of the central section formed integral with the front end sect-ion C". The portion f forms a stub by which the corner-section C is welded onto the back rail A. drieal' enlargements g g may be drilled vertically with holes for the reception of bolts or rivets by which to attach the side rail A to the brackets Z Z on the seat D; or the side rail may be formed with downward'projecting lugs t, as shown in Fig. 8 of the drawings, for attaching the side rail to the aforesaid brackets.

Having described my invention, What I claim as new, and desire to secure by Letters Patent, is-

In the manufacture of shifting-rails for carriage-seats, the method of forming the corner-section 0, consisting in, first, forging The cylin- 4o the blank, Fig. 3, with the side enlargement f on the central portion thereof and with the approximately-cylindri cal enlargement g near one end of the aforesaid side enlargement; secondly, splitting the side enlargement f longitudinally from one end partly the length thereof; thirdly, spreading the cleft h of the enlargement f from the main portion of the blank and bending toward the opposite side of the latter the end portion 2' adjacent to the fixed end of the aforesaid enlargement; fourthly, setting the portions f and tat right angles to and in opposite directions from the main portion of the blank; fifthly, rounding the edges of the blank by subjecting the same to the pressure of the dies of a drop-press, substantially as set forth.

In testimony whereof I have hereunto signed my name this 5th day of June, 1889.
